The excitement of investing in a company that can reverse its fortunes is a big draw for some speculators, so even companies that have no revenue, no profit, and a record of falling short, can manage to find investors. But the reality is that when a company loses money each year, for long enough, its investors will usually take their share of those losses. Loss making companies can act like a sponge for capital - so investors should be cautious that they're not throwing good money after bad.

Despite being in the age of tech-stock blue-sky investing, many investors still adopt a more traditional strategy; buying shares in profitable companies like Nextracker (NASDAQ:NXT). While this doesn't necessarily speak to whether it's undervalued, the profitability of the business is enough to warrant some appreciation - especially if its growing.

How Fast Is Nextracker Growing Its Earnings Per Share?

Even when EPS earnings per share (EPS) growth is unexceptional, company value can be created if this rate is sustained each year. So EPS growth can certainly encourage an investor to take note of a stock. It's an outstanding feat for Nextracker to have grown EPS from US$0.46 to US$2.84 in just one year. When you see earnings grow that quickly, it often means good things ahead for the company. Could this be a sign that the business has reached an inflection point?

Careful consideration of revenue growth and earnings before interest and taxation (EBIT) margins can help inform a view on the sustainability of the recent profit growth. The music to the ears of Nextracker shareholders is that EBIT margins have grown from 11% to 25% in the last 12 months and revenues are on an upwards trend as well. That's great to see, on both counts.

Are Nextracker Insiders Aligned With All Shareholders?

Since Nextracker has a market capitalisation of US$6.1b, we wouldn't expect insiders to hold a large percentage of shares. But thanks to their investment in the company, it's pleasing to see that there are still incentives to align their actions with the shareholders. As a matter of fact, their holding is valued at US$19m. That's a lot of money, and no small incentive to work hard. Even though that's only about 0.3% of the company, it's enough money to indicate alignment between the leaders of the business and ordinary shareholders.

Is Nextracker Worth Keeping An Eye On?

Nextracker's earnings per share have been soaring, with growth rates sky high. This level of EPS growth does wonders for attracting investment, and the large insider investment in the company is just the cherry on top. The hope is, of course, that the strong growth marks a fundamental improvement in the business economics. Based on the sum of its parts, we definitely think its worth watching Nextracker very closely. If you think Nextracker might suit your style as an investor, you could go straight to its annual report, or you could first check our discounted cash flow (DCF) valuation for the company.
